HAY BAKE AND COURIER.

Application filed January This invention relates to a combined hay rake and cooker and its primary object is to provide a machine of simple and very eflicient construction which when drawn across a mown field collects the swath left y the cutting machine into \vindrows and gathers the hay in the windrows into hay cocks of un formsize and form upon'a substantiallyv clean stubble.

I

In carrying out my invention I'employ two. cooperating elements 5 and (i'whichare pivotally connected by a king bolt 7' to facilitate' turning.

The element of'the machine forward with relation to the direction of its operative movement is designed to rake the swath into a windrow and the second element acting upon the wind'row gathers the hay into cocks, of uniform, size and dumps the same at reg has. a series of curved teeth of uniform size ular intervals.

The supporting frame of the machine is composed of two. sections 8 and 9 which are pivotally connected by the before mentioned king-bolt and it is supported at its ends upon traction wheels; 10. and 12.

The. forward frame section carries two rakes 13 which are mounted for rotation about rearwardly converging axes to conjointly gatherthe hay into a windrow in the center of the machine.

Each rake is preferably composed of three or more toothed members which, during r0 tation are held in their operative position by a gearin shown at 1.4 in Figure 1.

I attain this object by the construction and Rakes of. this character arerwell known 20,1920. Serial No. 352,885.

the art and inasmuch as thelspecificconstruction of their operating mechanism is not part ofthe present invention, the mechanism has not been shown in detail and will: not further be described;

The rakes 13'1 ceive their rotary move: mentf'rom the axle 15 of the front wheels of the machine by means of two pairs of beveled gear wheels 16 and 17 and the rakes are connected to their respective shafts byclutches 18 which are, adjustable from the drivers seat 19 ofthe machine through the medium of a fulcrumed pedal 20 anda system of levers 21.

Each clutch is by: means of a. key 18 shown in Figure 4, slidably mounted on the shaft upon which the respective rake 13- is lo sely supported and it normally engages with its correlative on the rake whereby the latter is compelled to rotate with the shaft. The clutches are attached to the forked extremities of levers 21 and these levers are, pivotally connected to the ends of a, bifurcated lever 21 which is pivotally connected at the lower end' of the pedal 20;

lVhen the pedal is moved about its fulcrum by foot-pressure, the rearward? movement of its lower arm causes the moving members of the two clutches to simultane ously disengage. the rakes with the result that the rotative continuity of the latter with the respective shafts is. broken.

The cooking element ofthe machine comprises two ralres. 22' and 23 extending transversely of the frame and cooperating to gather the hay in the windrow produced bythe first described raking element into hay cocks of uniform size and" form.

The forward rake on the cocking element set on a head 24 and the other rake, at the rear end of the: machine, has curved teeth which decrease in length from the center of its head 25 in'opposite directions to gather the hay into a cock by the arcuate arrangement of their points. 7

The traction wheels 12 at the rear end of the machine are mounted to revolve upon spindles 26 which are rigidly secured upon laterally projecting arms??? at the rear end of the frame and toothed wheels 28. connected at the inside of the, Wheels l2 serve. in thecneratiou of the machine to intermih tently lift the rakes of the cocking ele ent, as will hereinafter bev more fully descrihed;

' tends.

A forwardly projecting tappct 33 on the rod is placed to engage a relatively fixed stop 3i on the fr me of the machine to separate the pawls iiroin the rcsiectire wheels at a determinate point in the u movement of the rake with which 1 is connected, and an upwardly e, arm 35 on the rod provided to im engage an operating lever 36 which c ls the position of the forward ralte or the shocking element.

The head of the laslaner: fastened between two parli 3T ported in bearings 39 on the whit-ii is pirotally connected with 'he referred to operating lever 36 th medium of an arm l0 extending a to the others.

The lever is fulcrunied in coaxial relation to a toothed segment d1 which cooperates with a movable spring-pressed pawl on the lever to lock the parts in their adjusted positions.

A plurality of rods L3 extending slantingly from the frame into the dish of the curved rake 22 prevents excessive upward movement of the hay and cooperate with the rake teeth to gather it into compact cocks.

In the operation of my invention the machine is drawn over the hay left on the hold by the machine used. in cutting it, by draft animals or a tractor engine. The converging rakes at the front of the machine gather the hay into a windrow, the curved rake atthe rear of the same bunches the hay in the windrow into cocks which are deposited on the lield at regular interval and the inte mediate rake clears the ground forward of the cocking rake so that the hay cocks are dumped on a clean and well raked stubble.

The toothed wheels 28 rotating with the rear traction wheels carry the pa wls 30 which by gravity are held in engagement with the teeth thereof, downwardly and by the engagement of the rod on which the pawls are formed, with the loops 32, cause the head 25 of the cocking rake to turn about the shaft 26, thereby elevating the rake for the purpose of dumping the hay which it gathered into a cock.

The engagement of the upwardly project ment of the rakes, the cocking Yul leased by the cii ao cinent of the tunnel .3 3

it b c. l: with the stop 3% on the Joe and l:' .p:-: to

its original position in nich the 1 i its teeth are in contact with the ground.

The rake remains in this poi ion until the rod of the pawls again engages the front sides of the loops 32 in whi h it has its movement, when the above described operation is repeated.

Before the cooking rake i again clei'ated the d iver of the ma hinc occupying the seat 11 returns the auxiliary rahe to its operative position, thereby cleari g the, ground on which the hay cock formed by too other rake is subsequently dumped.

Having thus described my invention ."h: I ciaini and desire to secure by Letters-l eiit is:
